> in newMutableProjection, it will fallback to InterpretedMutableProjection if 
> failed to compile.
> Since we remove the configuration for codegen, we are heavily reply on 
> codegen (also TungstenAggregate require the generated MutableProjection to 
> update UnsafeRow), should remove the fallback, which could make user 
> confusing, see the discussion in SPARK-13116.
